Metallics JG8N173 – Frequently Asked Questions
1) Will the Metallics JG8N173 nut thread onto a 5/8 inch fine thread bolt?
Yes. The JG8N173 is a 5/8-18 hex nut, so it takes 18 threads per inch, which is the UNF (fine) pitch for 5/8 inch diameter. It will not run onto a 5/8-11 coarse thread rod or bolt, so if your anchor rod or hanger rod is coarse, you need the UNC version instead.
2) Do these Grade 8 hex nuts meet Buy American requirements for a federally funded job?
The JG8N173 is flagged compliant for both ARRA and Buy American in the product record. Country of origin is China. If your specification demands domestic melt and manufacture rather than the ARRA/Buy American compliance flag, verify against your project's exact clause before releasing it.
3) Is the zinc finish on these nuts suitable for outdoor or damp locations?
The finish is zinc plating over hardened steel. That's a mild corrosion barrier intended for dry indoor and protected service, electrical rooms, strut and hanger work, machine assembly. For sustained wet, coastal, or wash-down exposure, zinc plated carbon steel will eventually rust and a stainless or hot dip galvanized nut is the better call.
4) How many nuts come in a jar, and can I buy just a few?
They ship in a jar of 25, and 25 count is the order minimum, so that jar is the smallest buy. The jar weighs 1.83 lbs. Other sizes and quantities are available by request.
5) What dimensional standard do these hex nuts conform to for submittals?
Dimensions follow ANSI/ASME B182.2 and the steel is AISI 1021-1045. Those two lines, plus Grade 8 and Rockwell C24-32 hardness, are what a submittal reviewer or MRO buyer is normally looking for on a high-strength nut.
6) Is this a locknut or a plain finished hex nut?
It's a plain hexagonal nut, no nylon insert and no distorted thread locking feature. On vibration-prone equipment mounts you'll want a jam nut, a lock washer, or thread locker on top of it.
